How many meridians of longitude are there

The prime meridian runs through the Royal Observatory in the town of Greenwich, which is in southeast London. If you live on the equator you will experience the quickest rates of sunrise and sunset in the world, taking a matter of minutes.

While tropical areas along the equator can experience wet and dry seasons, other regions may well be wet for much of the year. The climate is warm and moist throughout the year, with little variation in temperatures. This means that the belt around the Equator is rich in resources to support biodiversity with all its different requirements. Begin typing your search term above and press enter to search.

Similarly, it is asked, what are the meridians of longitude and latitude? A longitude line, or a meridian, is any line that runs from the north pole to the south pole.

Technically speaking, there are an infinite number of these. The useful ones correspond to degrees, and that makes Longitudes are imaginary lines on the globe that run from North Pole to South Pole. Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertical ly up and down and meet at the North and South Poles.

These lines are known as meridian s. Each meridian measures one arc degree of longitude. The distance around the Earth measures degrees. The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at degrees.

It is the basis for the International Date Line. Half of the world, the Eastern Hemisphere, is measured in degrees east of the prime meridian. The other half, the Western Hemisphere, in degrees west of the prime meridian. Degrees of longitude are divided into 60 minutes. Each minute of longitude can be further divided into 60 seconds. A degree of longitude is about kilometers 69 miles at its widest. The widest areas of longitude are near the Equator , where the Earth bulges out.

Because of the Earth's curvature , the actual distance of a degrees, minutes, and seconds of longitude depends on its distance from the Equator. The greater the distance, the shorter the length between meridians. All meridians meet at the North and South Poles. Longitude is related to latitude , the measurement of distance north or south of the Equator. Lines of latitude are called parallel s. Maps are often marked with parallels and meridians, creating a grid.

The point in the grid where parallels and meridians intersect is called a coordinate. Coordinates can be used to locate any point on Earth. Knowing the exact coordinates of a site degrees, minutes, and seconds of longitude and latitude is valuable for military , engineering , and rescue operation s.
